The annual show by the Society of Independent Artists in New York was advertised as “without juries or prizes”. Anyone who paid the $6 membership could enter. Duchamp submitted the piece in secret while acting as the Director of the Society, and was refused entry.

More ironically, the original was lost and eight replicas were re-created from baked earthenware, once again defying the point of the original use of "readymade" art.
(Marcel Duchamp / Urinal)
